Settlement of Iceland
The first Viking settlers arrived in Iceland in the late 9th century when the Norsemen migrated around the North Atlantic and discovered Iceland by accident. The settlement period of Iceland is believed to have lasted for about 60 years from around 870 to 930. Records from the early history of Iceland can be found in old literary sources, Íslendingabók - The Book of Icelanders and Landnámabók - The Book of Settlement.
Most of the first settlers came from Norway but also from Denmark, Sweden and from the Viking settlements around the British Isles. Prior to the arrival of the Vikings it is actually believed that Iceland was not uninhabited as some Irish monks were already living there but they left soon after the Nordic settlers arrived.
